Nova receives a bill for her cell phone each month. she pays a flat fee of $35 plus $0.05 per text message. this month, her bill without taxes was $51.50 which equation gives the number of text messages, t, she sent this month?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
